Harold Albert “Jack” Ashford was a long-serving cutting engineer at EMI (Australia), whose career extended from the late 1920s until his retirement through ill health in 1973. Associated with the company’s Homebush operations and later its Castlereagh Street studios, Jack reportedly helped introduce local microgroove record production and is likely to have cut many Australian Beatles releases. He also trained his successor, Warren Barnett, passing on decades of practical experience in disc mastering.
